A doctor who appears to have been the target of a former physician who started shooting at a hospital, killing one person and injuring six, says he has no idea why he would have been singled out. Dr. Kamran Ahmed tells the New York Post he wasn't the only one Dr. Henry Bello had a problem with. However, "he never argued with me," Ahmed says. "I don't know why he put my name." A law enforcement official tells the AP that Bello arrived at Bronx-Lebanon Hospital Center in the Bronx on Friday with an assault rifle, which was bought in upstate New York about a week earlier, hidden under his lab coat and asked for a doctor he blamed for his having to resign (presumably Ahmed), but the doctor wasn't there at the time. Authorities say Bello went to the 16th and 17th floors and started shooting anyway, killing Dr. Tracy Sin-Yee Tam, who, like him, was a family medicine doctor.

Hospital officials say that Tam normally worked in one of the hospital's satellite clinics and was covering a shift in the main hospital as a favor to someone else. Before the shooting, Bello sent an email to the Daily News, blaming colleagues he said forced him to resign two years earlier. "This hospital terminated my road to a licensure to practice medicine," the email said. Bello's former co-workers described a man who was aggressive, loud, and threatening. Bello had warned his former colleagues when he was forced out in 2015 that he would return someday to kill them. Ahmed says Bello "had a problem with almost everybody" and "that's why they fired him, because so many people complained." Bello died from a self-inflicted gunshot. The six injured people were hospitalized. (Read more shooting stories.)
